Maternity Coat

Now i know we are supposed to have enough padding but the cold night are drawing in and with a chilly bonfire night on teh way i cant help thinking it might be a good idea to invest ina maternity coat - being due in Feb i think i will get my wear out of it! So imagine my surprise when i look on every maternity website i can think of to find a half decent coat - and find nothing!!!

Can anyone help with my dilema at all? Brrrrr it's getting cold in here!
